Questions about Compress PDF to 50 KB
Will the PDF still be readable at 50 KB?
For normal text documents, yes. MiniPDF lowers picture quality step by step only until the file fits, and shows the final size before you download. Open the file once to check it before uploading.
My file is still too big. What can I do?
Turn on "Black & white" — text documents become much smaller. You can also upload only the pages the portal asks for, using Split PDF.
Is my document uploaded to your server?
No. Compression runs inside your browser, so the file never leaves your phone or computer.
